Prior to start-up
Below procedures are general guidelines for the start-up and shut-down functions of SWRO-systems
with the Danfoss iSave Energy Recovery Device.
Procedure details may differ depending on the system design.
The numbers marked in () refer to the diagram below.
Prior to initial start-up all piping connected with the iSave unit must be thoroughly flushed to ensure
that no impurities enter the iSave. Inadequate pre-flushing will strongly influence the life of the iSave
and might lead to breakdown of the iSave.
1. Install all filter cartridges in the system.
2. With the iSave disconnected from the piping, the system must be flushed in order to remove
possible impurities from the system (pipes, hoses, membranes etc.).
Flushing must run until the system can be ensured clean.
3. Connect the iSave to the pipework. The iSave is now ready for start-up.
